Title: Heat pipe type cooler
Inventor: SASAKI KAZUYOSHI
IPC: F28D15/02
Filed: 1989-03-07
Abstract: PURPOSE:To prevent a heat pipe from bursting due to freezing of working liquid inside the heat pipe by providing a reinforcing member which is fitted to the circumference of the lower end of the heat pipe. CONSTITUTION:A guard member 6 is attached on the lower end of a heat pipe 3 with a filler 7. The guard member 6 is fitted to the outer circumference of the heat pipe 3 to increase the strength, and an iron pipe is applicable for it, for example. Thereby, if working liquid 3a in the heat pipe 3 freezes, the heat pipe does not burst. The reason why the guard member is provided only on the lower end is that the working liquid 3a accumulates in the lower portion as the heat pipe 3 is vertically installed. The round end of the heat pipe 3 has a sufficient strength because the thickness becomes thick when the pipe is sealed. Silicon sealant, for example, is used for the filler 7.

Title: Photodetecting circuit
Inventor: FUKUYAMA TOSHIBUMI
IPC: H03G3/20
Filed: 1982-04-01
Abstract: PURPOSE:To remove the variation of an amplification factor for pulse light and to improve SN ratio, by forming the titled circuit by a parallel circuit consisting of a transistor, a photodiode and a resistor and a capacitor. CONSTITUTION:The titled circuit is provided with the parallel circuit consisting of the photodiode 7 connected to the base of the transistor TR1 and the resistor 6 and the capacitor 8 connected to a connection point different from the base of the TR1. In said circuit, the DC component of optical current ordinally generated in the photodiode 7 by disturbance light is made flow into the resistor 6 and scarcely flows into the TR1. Therefore the bias point of the TR1 is not changed. On the other hand, the AC component of optical current generated in the photodiode 7 by pulse light is made flow into the TR1 through the capacitor 8. Thus the TR1 is prevented from bias change due to disturbance light, making it possible to reduce the change of the amplification factor for pulse light and improve the S/N.
